------- Comment #3 from pinskia at gcc dot gnu dot org 2008-12-11 23:04 ------- Your testcase does not show any issues at all. doubles are not required to be aligned to 8 byte boundaries at all, they are only required to be aligned to 4 byte boundaries. Now with -malign-double they will get aligned but you just changed the ABI to have that requirement.
